Quad ShieldingLowers Noise

High-performance AC power cords must deliver current on demand and filter out everything except 50 to 60Hz. This is not a trivial accomplishment and requires, among other techniques listed under Features, a high degree of shielding. Noise is everywhere; riding the AC supply and ground, high-frequency radiated noise from digital devices, and noise produced by your own A/V system. PowerLine Mk IIs carry two shields and two grounds to get the noise out! Cleaner, less distorted power delivers more transparent, colorful and dynamic sound.
